NASA announced ECHO I balloon satellite had been used this summer by French National Geographic Institute to accurately locate satellite tracking stations being built for France and ESRO across Europe and Africa. According to reports, French National Geographic Institute photographed ECHO I simultaneously from precisely located cameras in France and Algeria, in order to join the triangulation systems of France and Algeria. Its aluminum-coated mylar skin wrinkled and misshapen, ECHO I was no longer useful in radio-reflecting communications, but it was still clearly visible in the nighttime sky after more than four years of orbiting the earth.
